1. In case of electrical failure, check whether there is phase loss fault in the motor and line, whether the reverse connection of the wiring leads to the reverse rotation of the pump, and whether the protection system operates wrongly. Test the machine after ensuring that the frequency of the power system reaches the normal value.
2. The sand suction pump has not operated for a long time, which makes the impeller and sealing parts bonded, resulting in motor stalling; Before starting up, turn the sand suction pump to confirm that it rotates flexibly.
3. The sand suction pump itself is defective, and there is a dead center during turning. Disassemble the pump body, check whether the parts of the sand suction pump are damaged, and replace the damaged parts in time.
The outlet pressure of sand suction pump is small and the flow is insufficient
Surface roughness of sand conveying pipeline of sand suction pump: if the surface of the inner wall of the pipeline is rough, the resistance coefficient of the pipeline will increase. Therefore, when selecting the sand pumping pump and sand conveying pipeline, the pipeline with smooth surface should be selected to effectively reduce the resistance of the pipeline. The biggest feature of UHMWPE pipeline is that its surface is smooth and does not adhere to small particles. It is the best choice for sand pumping pump and sand conveying pipeline.
2. Particle size of mud and sand slurry: the larger the particle size of the conveying medium, it will increase the settling speed of particles in the mud, cause pipeline blockage, and then increase the pipeline resistance loss of sand pumping pump sand conveying pipeline. Therefore, reducing the particle size of particles in the mud can effectively improve the pipeline blockage and reduce the pipeline transmission resistance of mud.
